According to the International Agency for Research on Cancer IARC. titanium dioxide is classified as Class 2B. meaning it is likely to cause cancer in humans. This determination is based on studies showing that inhaling the dust has led to respiratory tract cancer in rats. It should be noted. however. that the IARC points out the limited evidence in humans and recommends further research. While not all exposure to titanium dioxide may be harmful. caution may be necessary. particularly in occupations with significant levels of dust exposure.

Due to its distinctive physical attributes. titanium dioxide is extensively utilized across various industries. Included in paints. plastics. paper and inks. it serves as a crucial component for providing opacity and resilience. Additionally. the cosmetics industry utilizes it as a colorant. sunscreen and thickener. while the food manufacturing sector utilizes it solely as a colorant. Its photocatalytic functionality also makes it highly effective in air and water purification systems. This substance is inert and non-toxic. making it a popular addition in personal care products like toothpaste and certain medications.

As of my last update in 2023, I cannot provide real-time current prices for polypropylene due to the dynamic nature of commodity markets.

Additionally, subscribing to industry-specific newsletters or market analysis reports can provide regular updates and insights into price trends, helping businesses and consumers make informed decisions.
